Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-7, this embodiment provides a single-phase solid-state relay, including original silicon controlled rectifier base 1, original silicon controlled rectifier base 1 has been inside to have seted up and to accomodate groove 11, the equal fixedly connected with a pair of stopper 12 of lateral wall is controlled to accomodate groove 11, accomodate and be equipped with circuit board 13 in the groove 11, circuit board 13 lower surface and the laminating of stopper 12 upper surface, mounting groove 130 has all been seted up to circuit board 13 upper surface left and right sides, threaded groove 131 has been seted up to circuit board 13 upper surface four corners department, be equipped with integral type shell 2 directly over original silicon controlled rectifier base 1, a pair of standing groove 23 has all been seted up to integral type shell 2 upper surface front and back both sides symmetry, standing groove 23 one side is equal fixedly connected with joint board 24, standing groove 23 inside wall has seted up hinge groove 21, it has fire-retardant shield 3 to articulate in the hinge groove 21, mounting groove 30 has been seted up to fire-retardant shield 3 upper surface, fire-retardant shield 3 and joint board 24 joint, be equipped with threaded post 25 in the standing groove 23, threaded post 25 and threaded groove 131 threaded connection, original silicon controlled rectifier base 1 lower fixed surface is connected with absorber plate 15.

The working principle is as follows: when using, the staff places circuit board 13 on stopper 12, fix circuit board 13 afterwards, let integral type shell 2 press again on the original installation silicon controlled rectifier base 1, make articulated 21 articulated fire-retardant shield 3 open, fix through screw thread post 25 and screw thread groove 131, make absorber plate 15 fix and use in the place that needs to use at last, the device has been reduced in the use, when needing to be changed if its inside spare part breaks down, its installation is difficult, can't change the maintenance to inside spare part, need change whole device, the condition of increase device cost.

In order to dismantle the device and maintain and change spare part in the device, so sliding tray 10 has been seted up to former dress silicon controlled rectifier base 1 upper surface, sliding

tray

10 and 2 sliding connection of integral type shell, take out integral type shell 2 from former dress silicon controlled rectifier base 1, change the electronic component of inside, it is more convenient to make the device use.

Consider that the slip on the device can lead to the 2 landing of integral type shells on the device, so the equal fixedly connected with in former dress silicon controlled rectifier base 1 left and right sides surface a pair of joint piece 100, a pair of joint groove 20 has all been seted up to the surface about integral type shell 2, joint piece 100 and joint groove 20 joint, it is spacing with the integral type shell 2 on the device through joint piece 100 and joint groove 20, prevent that integral type shell 2 from dropping from former dress silicon controlled rectifier base, improved the security of device.

Although the device is because vibration probably takes place to drop after the screw thread post 25 is fixed for a long time in the use, leads to the spare part in the device to drop, so screw thread post 25 lower extreme cup joints metal anti-skidding gasket 26, through metal anti-skidding gasket 26, can prevent that screw thread post 25 from taking place to drop because of the vibration after fixed for a long time.

The device can be installed in the place that needs use in service, so mounting hole 151 No. two has been seted up on absorber plate 15 upper surface left side, and mounting hole 150 has been seted up on absorber plate 15 upper surface right side, carries out fixed mounting to mounting hole 150 and mounting hole 151 No. two through the screw rod, makes the device use more convenient.

In addition, the copper density is high, the heat absorbing plate 15 can absorb more heat due to the same volume, the copper sheet can absorb the heat emitted by parts in the device after long-term operation, and the service life of the device is prolonged.

When the single-phase solid-state relay in this embodiment is specifically used, when using, the staff places circuit board 13 on stopper 12, fix circuit board 13 afterwards, let integral type shell 2 press on silicon controlled rectifier base 1 again, integral type shell 2 slides with sliding tray 10, it is fixed to carry out the joint with joint piece 100 with joint groove 20 afterwards, make articulated groove 21 articulated fire-retardant shield 3 open, fix with thread groove 131 through threaded column 25, utilize metal anti-skidding gasket 26 to carry out locking processing to threaded column 25, rethread installation hole 150 and No. two installation holes 151 on the heat absorbing plate 15 with the device installation needs the place of installation and use, heat absorbing plate 15 is the copper material structure, copper density is high, the same volume can absorb more heats, can absorb the spare part in the device, the extension device life, when making the spare part in the device break down and need change, no longer need change whole device integral type, only need take out circuit board shell 2 and change the electronic component on circuit board 13, the use cost of device is reduced.
